Using POI for excel works in Java

Question

I want to read/write excel files in Java (netbeans). There are a lot of information on how to do that with APACHE POI and I know that. My question is that, where should I put poi jar files? should I extract it in my local project?

Additionally, should I download the binary or src of the poi?

I agree that Maven is the perfect choice, but if you don't have time to study about it, just try to add the jar file to your project

OK. I downloaded poi binary package. It contains poi-3.16.jar (~2MB) and many other jar files. Is that enough to add that or I have to add all library files? – mahmood Apr 20 '17 at 10:56
I believe that you just need one. – Tuan Hoang Apr 20 '17 at 11:00
Although I added the jar file, but it doesn't work. I will ask in another post – mahmood Apr 20 '17 at 11:19
I guess because the reference between the project and the library has not been made. – Tuan Hoang Apr 21 '17 at 02:13

If you are using maven you only have to add this dependency to your pom.xml file

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.15</version>
</dependency>

With this library you can process .xls and .xlsx files. If you are not using maven you should download the jar file and add it to your classpath
